The discussion centers on the suitability of the book "Gravitation" by Misner, Thorne, and Wheeler (MTW) for studying relativity, particularly for someone with a background in calculus and differential equations. While "Gravitation" is praised as a comprehensive resource, it is deemed too advanced for beginners. Participants recommend starting with "Gravity: An Introduction to Einstein's Relativity" by James Hartle for a more accessible introduction. Other suggested texts include "General Relativity: An Introduction for Physicists" by Hobson, Efstathiou, and Lasenby, and works by Sean Carroll, J. L. Martin, Wolfgang Rindler, and Lewis Ryder. The conversation emphasizes the importance of selecting the right material based on the reader's level and the need for supplementary resources, such as online lecture notes and course sites, to enhance understanding of general relativity concepts.
